论文摘要
Au2O3掺杂的PBO-B2O3-SEO2：ER2O3（PBSE）玻璃陶瓷的各种弹性系数被用超声速度测量评估为AU2O3含量的功能。随着AU2O3的浓度，弹性系数和微硬度表现出降低的趋势。这种下降归因于这些样品中充当修饰符和诱导的缺陷的2组的金金属颗粒的浓度增加。观察到获得的结果与来自光谱研究得出的结论一致，这些研究包括X射线光电学光谱（XPS），红外（IR），光致发光（PL）和正电子歼灭（PAL）光谱学研究。总体而言，这些研究表明，即使存在金属颗粒的存在对于实现上的发光和电性能，这是可降低这些玻璃陶瓷的弹性系数和微硬度的这种颗粒的存在。但是，当Au2O3的浓度升高超过0.075 mol％时，我们观察到弹性系数和微硬度的略有增加。
Various elastic coefficients of Au2O3 doped PbO-B2O3-SeO2:Er2O3 (PBSE) glass ceramics were evaluated as functions of Au2O3 content using ultrasonic velocity measurements. The elastic coefficients and micro-hardness showed a decreasing tendency with the concentration of Au2O3. Such decrease is attributed to the increasing concentration of gold metallic particles and [SeO3]2- groups that acted as modifiers and induced imperfections in these samples. Obtained results were observed to be consistent with the conclusions drawn from spectroscopic studies that include X-ray photoelectron spectroscopy (XPS), infrared (IR), photoluminescence (PL) and positron annihilation (PAL) spectroscopy studies. Overall, these studies have revealed that even though, the presence of gold metallic particles is preferable for achieving superior luminescence and electrical properties, presence of such particles caused to decrease the elastic coefficients and micro-hardness of these glass ceramics. However, when the concentration of Au2O3 is increased beyond 0.075 mol%, we have observed a slight increase of elastic coefficients and micro-hardness.
